AS SSD is a great free tool designed just for benching Solid State Drives. It performs an array of sequential read-and-write tests, as well as random read-and-write tests with sequential access times over a portion of the drive. It uses incompressible data samples which many drives struggle with, so results can be viewed as the worst case scenarios.
AS SSD includes a sub suite of benchmarks with various file pattern algorithms but this is difficult in trying to judge accurate performance figures.
Using the AS SSD benchmark the drive's read score of 2856 sees the drive in second place on the results chart but its write score of 4498 is the fastest we've seen to date for a M.2 2230 drive.
